pseries: Small cleanup to H_CEDE implementation
The H_CEDE hypercall implementation for the pseries machine doesn't trigger quite the right path in the main cpu exec loop. We should set exit_request to pop up one extra level and recheck state, and we should set the exception_index to EXCP_HLT (H_CEDE is roughly equivalent to the hlt instruction on x86). In practice, this doesn't really matter except for KVM, and KVM implements H_CEDE internally so we never hit this code path. But we might as well get it right, just in case it matters some day.
